Answers review of revision 5. Still framing only; no implementation.
**Q#BP-R1 IS RULED: a single click SELECTS a listview row only.**
RET/SPC remain the activation path (`listview.lua:610`); no
click-to-visit, no double-click-to-visit. That is acceptance 48's own
wording, and it keeps document navigation from arriving as an
incidental consequence of wiring replay.
**REVISION 5 CONCLUDED THAT ACTIVATION ORDERING MADE REPLAY SAFE. IT
IS NECESSARY BUT NOT SUFFICIENT.** The ordering holds only for gestures
that activate, in a session nothing interleaves with, on a presentation
that does not change mid-gesture, with modifiers intact and the mode
line excluded. Each of those four provisos is an edge:
**R-a --- modifiers are dropped before the shared path.** `PanelPointer`
carries `mods`; the daemon destructures them into `..`
(`src/daemon.rs:2425`) and the dispatcher has no modifier parameter.
This breaks PRECEDENCE, not just fidelity: `apply_terminal_gesture`
gates child reporting on `!shift && ... && modes.mouse_sgr`
(`src/editor.rs:3534`), so Shift is the user's "select locally instead
of talking to the child" override. Zeroed, a Shift-drag over a
reporting terminal panel sends SGR. Row: Shift-drag selects locally and
the child receives NO bytes. Mutation: drop `mods` at the boundary.
**R-b --- `Drag` and `Up` do not activate**, and another frontend's
input can interleave between a Down and its Drag, so a replay reading
ambient active-window state acts on whatever is active then. The
framing now NAMES the mechanism: an explicit side-window cell->byte
adapter, and selection through a window-TARGETED path.
`activate_and_position` (`src/editor.rs:3795`) is both the precedent
and the trap --- its conversion is properly window-scoped, but it calls
`set_active_window_id`. Rows: panel A Down -> frontend B input -> A
Drag/Up changes only A; an orphan Drag/Up on a passive panel leaves the
document mirror byte-identical.
**R-c --- `panel_grid_size` is the FRAME, not the terminal viewport.**
The panel's last row is its mode line: projection derives content as
`rows - 1` (`src/editor.rs:2499`) while `panel_hit_test` reports across
the whole frame (`pmacs-gpu/src/main.rs:7184`), so a `PanelPointer` can
name the mode-line row. Passing the full grid to
`apply_terminal_gesture` would make the mode line a child terminal
cell. Terminal viewport is `rows - 1`; document replay follows the
TUI's existing rule, "Mode-line click: reserved"
(`src/editor.rs:3304`). Rows must distinguish content from chrome or an
off-by-one passes.
**R-d --- replacement leaves the frontend's gesture latch armed.**
`Absent` clears `pointer_held` and `last_pointer_cell`
(`pmacs-gpu/src/main.rs:6909`); `Present`->`Present` does not
(`:6913`). Press on A, A replaced by B, and the latch emits a Drag or
release for B with no B press --- and acceptance 49 CANNOT reject it,
because the event carries B's current epochs. 49 is a staleness gate
and this is not a stale event; it is a well-formed event from a gesture
whose presentation no longer exists. The fix has a precedent in the
same file: the DIVIDER drag latch already carries both epochs and
self-invalidates (`:7288`). The pointer latch never got it.
Three of the four are places where the tree already contains the right
answer and the panel path does not use it, which is worth saying
plainly: this is wiring that has to be done carefully, not mechanism
that has to be invented.
